Bubble Beyond

Bubble Beyond is an interactive video installation that allows visitors to engage in an augmented reality where they can play with dozens of virtual bubbles. The bubbles emanate from the heads of visitors as they come into view. The bubbles capture their faces and float around randomly and then morph into expressive emoji. Visitors can pop their bubbles as well as other people’s bubbles.

Up to six visitors are tracked by a Kinect V2 system, which captures both their motion and image using the 1080p video camera. A custom algorithm generates the virtual bubbles which are projected on an 8 x 4.5 foot screen. After 30 seconds without human interaction, clouds of emoji float by. Bubble Beyond is a playful representation of our interaction and individual expression in the Internet Age.

TRANS-ELEMENTAL / Mixed Reality Installation

Artwork by collisi1

Can natural elements from a virtual reality take solid form and exist in our physical reality? Can virtual particles affect real world molecules?

This project is a mixed reality installation in which the wind of Second Life is used to move a windchime in real physical space. The virtual wind’s direction and speed are the variables that determine the device’s functionality in real time. This work creates a parallel between these two realities (virtual and physical), showing how they relate and interact with each other, creating a portal from one world to the other.

Modica Way

explore how a graffiti mural changes over time as existing images are painted over by new artists.

My aim for this project was to create an interface that works as an intuitive metaphor - pushing forward moves the user forward in time by displaying more recent images.

The artwork I used is from a graffiti mural in Central Square, Cambridge MA. The mural is frequently repainted, and by photographing the mural weekly I was able to capture the mural as it changed over time. Sometimes the changes were gradual evolutions; at other times the mural changed suddenly when large sections were completely painted over.

DreamDrops

DreamDrops is an interactive fiber/video installation where viewers can interact with felt sculptures, brought to life as a colorful, immersive video and audio environment.

Three DreamDrops are constructed with felt and paper. The felt gives them the form, and the paper provides a window into the virtual words. The Drops are suspended by their “tails”, from the ceiling at three heights. The red Drop is hung the most high, the blue Drop is lower, and the green Drop hangs the lowest.

As visitors walk among the DreamDrops, they can see the three animated worlds. The red world looks like clouds at sunset, the blue world looks like the depths of the oceans, and the green world looks like a lush, tropical forest. The three worlds are populated by “boids”, a flock/school of animated critters that dash about in small groups.Visitors are invited to poke their heads up into DreamDrops. They’ll see bursts of color and dynamic sparks triggered by their motion which is detected by a Microsoft Kinect sensor. People can interact with the boids, who will playfully investigate the human visitors, calling out with a futuristic wail. A hand clap gesture will trigger a colorful tunnel effect that will transport the visitor to other worlds.

With their installation, Rob and Kristina are exploring the threshold between personal space and public space in the technology era. The installation allows people to experience a private environment of light and color in a very public arena.

Several open source software projects were used in this installation:

  • OpenFrameworks - an open-source C++ library for creative coding
  • ofxKinectNui - Sadam Fujioka’s addon using the Microsoft Kinect
  • ofxMSAFluid - an addon for solving and drawing 2Dfluid systems by Memo Akten
  • ofxBoids - a flocking motion addon for by Satoshi Okami

Rob and Kristina would like to thank Jennifer Lim for her help with this installation.

Junkspace

HD video projector, Mac miniO
Artwork by collisi1

Junkspace is a time and location sensitive animation and mobile application that dynamically visualizes space debris tracking data, using images of earth-bound electronic waste as stand-insfor debris in orbit above the viewer. Using custom software, NORAD's database of debris orbit descriptions and the GPS coordinates of the exhibition venue or viewer position, the movement of animated e-waste on screen aligns with theorbital path of actual pieces of debris in orbit above the user's location. As an object passes over the center of the screen, the name of the correspondingpiece of debris appears at the bottom. The free iOS app utilizes the device's built-in compass, GPS and accelerometer and allows the user to scan the entiresky around and beneath them. Users can also find out more information on the originating satellite or rocket, including launch date, country of origin, and purpose by tapping on its name. The aim of Junkspace is to draw attention to problems resulting from technological obsolescence (on earth and in space) and to inspire dialog about improved design protocols for future technologies.

INFLECTIONS

INFLECTIONS

INFLECTIONS is a generative system that temporally rearranges video sequences. The technical concept depends on the idea of a one-dimensional pseudo-random walk. We consider a movie timeline as a path. The program identifies a set of “inflection points” along this path. An inflection point is a moment without motion. At each inflection point, the software decides in real-time whether to go forward or backwards using a pseudo-random algorithm. It therefore temporally reorders the original sequence. This approach radically alters the images’ affective character, making them appear hesitant and uncertain. It shows how cinematic time determines the expressive meaning of images. The pseudo-random formula has tunable parameters which may produce diverse visual results. Different versions can thus be shown side by side, illustrating how the original sequence was only one out of many possible orderings. This method was inspired by the idea of possible worlds in modern logic.

A video explanation of the project can be found here:

Dial-A-Style - An Algorithmic Portrait Studio is an interactive video installation that allows visitors to create digital self-portraits in a variety of painterly styles. Through experimentation, viewers will come to understand and appreciate how various styles of painting impact the emotional connection to the artwork.

For online images created by this system, please see http://www.robgon.com/DialastyleImages.aspx

Directions:

  1. Click the Start Button
  2. Position the Webcam
  3. Spin the Wheel
  4. Click the Upload Button

There are four major styles represented on the wheel:

  • Impressionism - in the style of Van Gogh
  • Cubism - in the style of Picasso and Braque
  • Pointillism - in the style of Chuck Close
  • Anime - the Japanese comic style

The wheel can stop in between neighboring styles, which results in a hybrid styled portrait.

Open Source Components:

  • openFrameworks
  • OpenCV library
  • XDoG: eXtended difference-of-Gaussians flandmark face detector

I would like to thank Jennifer Lim for her help with this installation.

JitterBot - A Dialog in Dance

Rob Gonsalves: JitterBot - A Dialog in Dance

Overview

JitterBot is an interactive installation that allows visitors to dance with a virtual robot. This piece explores the threshold of leading / following in dance, allowing the participant to have a dialog with a technological being, using their bodies as the means of communication.

Song Selection

The user chooses a song by raising an arm and pointing to one of the seven original compositions. The computer uses a motion tracking interface and custom software to choose the song.

The Dance

The user is invited to dance along with JitterBot, the red robot. The user's movement is tracked using the tracking interface and displayed on a projection surface as the green robot. Sometimes JitterBot follows the visitor's lead and sometimes JitterBot busts a move on its own, for the visitor to follow.

The Setup

The installation is centered on using the Microsoft Kinect sensor which allows for real-time full-body 3d motion capture. A layer of custom software interprets the 3d skeleton of the viewer and renders a stylized human form, the green robot. The movement of the red robot is driven partially by the viewer's motion, but it is also driven by a library of canned moves to give a sense of autonomy. The two robots are rendered as a series of elongated spheres using OpenGL. The resultant video image is projected on a screen on the wall, and the accompanying music is played through speakers.
